The box-like cover in which a so-called portable typewriter is enclosedis separate from the same use, and one can imagine easily howtroublesome such an arrangement may be to anyone who has to work in thetrain or at the hotel or on a desk.

It should also be considered that in the future the typewriter of theportable type will not merely be a machine especially designed fortravellers but also, by virtue of its compactness and low cost, it willconstitute a popular instrument that,

`provided it is at least designed rationally, will nd its place at homejust the same as any other Vmodern machine that contributes tocomfortablelness and agreeableness.

Here again, only a low typewriter that cannot be operated if not coupledwith its cover win be suitable, since it can be arranged most easily in.a piece of furniture, e; g. in the drawer of a table,

Figure 3 is also a side elevational view showing the typewriter as it istaken out of its case or placed back into it.

Figure 4 is a plan view of the typewriter carrying handle.

' Figures 9 and 10 are fragmentary front elevational views of thetypewriter in its working and closed positions respectively, the casebeing shown in sectional view; in this embodiment ,the enclosing isobtained with the aid of parallelograms.

Figures 1.1 vand 12 are views similar to Figs.

4 Claims. (Cl. 197-186) 9 and l0 and relate to a modication in which theclosing is obtained simply by hand operation.

Figure 13 is a sectional view taken on line B--B in Fig. 3 and shows theconnection of the baseplate with a side-plate and the case.

Fig. 1 shows that while in a highly depressed typewriter the space isstill available vertically to accommodate the printing keyboard in itsinoperative position, it would be impossible to depress the longer keylevers completely withoutttheir being stopped by the typewriter baseplae.

On the other hand, it has been mentioned precedingly that a typewriterwhich could not be operated unless it has its cover attached theretowould afford considerable conveniences in its use. Up to the present ithas been found suiicient to secure the typewriter on the bottom of acase,

which bottom most frequently provides the baseplate that carries thetypewriter, and to cap the latter with a simple enclosing cover whichbecomes wholly useless and highly cumbrous in worktime.

According to this invention, the machine is mounted immovably on a part21 of the case which provides the bottom or baseplate thereof. Saidbottom 21 carries a movable lid 28 (Figs. 1, 5, 6, '1, 9) which is shutwhen the typewriter is not in use and which opens automatically when anyone of the keys is depressed.

It will be seen in Fig. 1 that when lid 28 is open printing can beperformed normally, the bars Sbeing able to operate unhindered.

The typewriter secured on its base-plate 21 is enclosed in a cover orcase 19 which protects the same from shocks and dust. Said case has lessbreadth than the base plate, so that a bearing margin is left betweenthe same and the edge of the base-plate all around the typewriter whichis useful for seating the latter in both its enclosed and its operativepositions. Fig, 13 shows the cover or case 19, the base-plate 21, andthe left side-plate 29 on which the eye |66 serves for the pivoting ofthe links |61, |62 of the parallelogram |56, |51, |6I, |62 by means ofpin |63 (Figs. 2, 5, 8). If the typewriter were enclosed in itsbase-plate and case it could not be operated as described hereinbeforeunless the lid 28 were open (Fig. 7), since the key levers S tend toproject below the base-plate. Consequently, for enabling said lid 28 toopen, space must bc provided for the same further below; such space canbe secured with the aid of retractable legs or of any other suitableprops.

However, since portable typewriters must be provided with a cover, it iscongruous to use the latter both for enclosing the typewriter after itsuse and for transporting it as well as for supporting it .when inuse,whereby a twofold advantage 'is secured, in that on one. hand the spacenecessary for the opening of the lid is provided and on the other handit is not possible to operate the typewriter unless its cover isattached thereto.

This leads to making the lid unremosabl'e from4 the typewriter.

The closing and openingbi the.case can ,be performed in two ways, viz.:lst, by means ci a pair of deformable parallelograms, 2nd, by simplyoverturning the typewriter by hand upon or into its case.

Both ci these arrangements will be described.

1st (Figs. 2, 3, 5, 8). The typewriter being assembled with itsbaseplate 21 and casingia.

its position is secured during the time it is taken intocr out of the-case 52 by the pair of parole lelog-rams fulcro-med at les-fand |55 onsaidcase and each oil which comprises a pair ci arms |51 coupled with.each otherby teeth 4compelling them to move by-,equal amounts in'reverse directions and a pair of linksv |6l, |62 vpivoted atene end onsaid 'arms.|61,a.|6 andat the otherend at@ |63 .on the base-plate 21.

Anchored-at |58 Yand |59'to arms |56 and |51 are-the ends of aspring |60thatV tendsto ,pull theparallelog-ram together. The Vtypewriter canpivot about |63 (Fig. 8) on the arc |64.

In order to preclude the `openingnof the )case as the typewriter isbeing carried about each parallelogram is provided (Fig. 2) with. asafetylatch composed, e. g. as the left one, of a slide |11 guidedon'the arm` |6| and formed-with aramp |18. As the slide |11 is;pushed bymeans of its turned up edge |111 or of;a handle that can be substitutedfor the same, said slide will move to the right until theramp |18thereon, by engaging a,- pin` |19 carried-.bythe arm |56,v latches thewhole device and retains the parallelogram from opening. Thelatchshownatthe right in the same figure comprises-a member |80 pivoted at |89onarn'i` |51 and iitted-.withapin |84 and a handle |8|. The pin- Idiispressed by a spring |85 ksecured :on the arm |51. As themember |80 ispushed to `the left fby meansof ythe handle |8'| it will assume.the-position shown,.and the ramp |86 thereon willclmbionaa'pin |83secured on the arm |62, thus lockingy the vparallelogram. The spring its.which acts 'upon |84 secures the member mil-inV its engagedand:its'disengaged positions.

As shownrin Fig. 2 the typewriter is-enclosed in; its case. Thearmsofthe parallelogram have opened andthe AVspring |60, tensioned over thepivots i@ and |55,A tends to lclose the parallelogram again, whereby thecase is compelled to remainl on the piece of furniture forfthe'time thetypewriter is being opened...

. By takingfholda of ,theztypewrit'er at .either end of. itsibase-plate2:1 and pulling; it upv same will befraised clear. ofritsycase: |52(Fig. 3)"and'this movement, assisted by the'tension'of spring |60,willproceed until the lstops |561. and: |511, by coming into: engagementwith each other, put air-end to it (Fig. 8).v Atthat moment, while thetwo side f parallelograms Vare 'Y sustaining the typewriterinitsraisedposition', same willbe overturned about-.|63 as--shownby thearrow |64, whereafter, by a. slight pressure exerted there` upon, itwill be sunk"` home-'vinto itsfoperating positionv (Figzf5l'.

Upon the work being nished, it is only necessary to proceed once againas described, whereafter, by upsetting the typewriter, the system willbe again such as it is shownin Fig..2.v

The advantages and; conveniences in use brought about by such acombination will be appreciated easily.

Figs. 7, 9, 10, 11 and l2 show how the typewriter as ay whole issupported on the base-plate. Aplastic strip is secured inside the caseat the edge thereof and provides the seat the typewriter is to restongwhether enclosed or displayed. Of course, saidstrip could be replacedby a strip of another suitable material.

2nd (Figs. 11 and'12). The process of taking thetypewriterinto. and outof its case may simply consist in taking-hold of the case or thetypewriter and bringing them into relation with each other as shown inFig. 11 where the typewriter is open and in use or in Fig. 12 where thetypewriter isxenclosed in itsrcase.

In this type ofenclosing the upper-edgev |521 stands higher than-.the:strip `ofplastic material |65, so that va retaining angeisleft'for thetypewriter, which preventsthe s latter from sliding sidewayson its coverinthe-,course of its operation.

The lid 28 shown in detail is Figs. 1, 6 and 'Tis as broad as necessaryfor.. the passagev of all the levers in the keyboard;- It is 'hingedat--28l to the base plate .21'. Itstravel is limited by-"a member|61pivoted on lid'28'.' Said member |61 is formed with two bevelnotches; Apin |68 on the base-plate 21`is;received1 in the upper -notchin member |61' when thelidis open and in the lower notch when the li'disclosed.' A spring-|69 anchored to the lug on member |61"urges'the latterintopermanentl engagement withVV pin |68. When the lid is closed itremains in the'position in which it is secured by the ramp onY the lowernotch; in order to-open said lid-it isonlyneces sary to press samedownwards, whereby the ramp on the lower notch'is caused tov` drivemember |61 aside to the left, whereafter1the-same-will snap back to theright while the pin |68 Yslips on the ramp in the upper notch inwhosebottom it comes to rest, thus'keeping-'thelidopen; the upper notch endsin a hook adapted to limit the travel in opening.

|53 designates buttonsmade of plasticmaterial and intended tox thetypewriterfon the desk during its operation by their adhesion.

Figs. 3 vand 4 show a handlefforA carryingv the typewriter. Said handle,located at the front, is received in a recess |1| provided-inthe-baseplate in the spacev left free 'by'A the keyboard in the enclosedposition of the typewriter;

Said handle ilfis mounted-on aA pair of strips |13, |14'. journaled on|15 and each of which is formed or provided with aboss= 131; |141respectively. When the typewriter is 'to be carried Vthe handle ispulled out of itsf-recessll, whereafter it is swung on the arc |16(Fig.V 3). 11i-'order to restore thevhandlesame `is pushedfbackintotheposition shown in chainlines;l where'it remains retained by the pressureof the pair' of bosses |131, |161 Y against-"the vside wallsV oirecessl1 The above-describedI arrangements are men*- tioned by way of exampleonly, since theshapes,
